It’s bad if the server response time is longer than three seconds. Google Search Console will display a critical error notification.
Server response speed, layout, CSS and JS optimization affect the loading time of the main part of the website.
Often the problem can be that the hosting resources are not enough, namely the CPU and the speed of the disk system. The most suitable advice is to find an SSD hosting and use CDN networks to reduce the time for content delivery, so the system will choose the server closest to the user.
